By interpreting your semantic HTML5 tags, Fixie will automagically add the right type of content in the right places. Headings, paragraphs, links, images, sections… trust me, it’s all there. That way you can focus on your design, instead of finding the right filler content.

A nice example on how this can be useful can be found in the equally clever utility: FlickHoldrhttp://flickholdr.com/

FlickHoldr simply gets placeholders related to the site you are developing, by pulling images from flickr based on tags… very simple and elegant…
